问题描述
由于Android的工作室新的更新后,增加了XML文件带来了一些混乱。
虽然设置的setContentView的参数()
,其中XML已经被使用? Content_main或Activity_main?
如果我想添加一个布局文件(XML)我必须创建具有相同名称的两个文件?
You should use content_main.xml
to put your views but passactivity_main.xml
as the parameter to you setContentView()
method.
activity_main.xml
is used to display coordinatorLayout, tabLayout, floatingActionButton, viewPager etc.
content_main.xml
is used to display your stuff i.e. what you want to display to users.
And if I want to add an Layout file (XML) do I have to create 2 files with the same name ?
Totally depends on the nature of the activity you are creating the layout for. The difference above will help you decide whether you need two or one.
